Why Do Animals Become Extinct? by Bobbie Kalman Pdf
The extinction of the dinosaurs may have been the result of an asteroid hitting Earth or an Ice Age freezing them to death. Today, animals such as elephants, zebras, tigers and leopards, some wolves, and many kinds of primates may still face extinction due to climate change, habitat loss, hunting, poaching, and pollution. This fascinating book introduces and explains the designations of endangerment--from extinct in the wild to vulnerable.

Science and the Endangered Species Act by Committee on Scientific Issues in the Endangered Species Act,Commission on Life Sciences,Division on Earth and Life Studies,National Research Council Pdf
The Endangered Species Act (ESA) is a far-reaching law that has sparked intense controversies over the use of public lands, the rights of property owners, and economic versus environmental benefits. In this volume a distinguished committee focuses on the science underlying the ESA and offers recommendations for making the act more effective. The committee provides an overview of what scientists know about extinction--and what this understanding means to implementation of the ESA. Habitat--its destruction, conservation, and fundamental importance to the ESA--is explored in detail. The book analyzes Concepts of species--how the term "species" arose and how it has been interpreted for purposes of the ESA. Conflicts between species when individual species are identified for protection, including several case studies. Assessment of extinction risk and decisions under the ESA--how these decisions can be made more effectively. The book concludes with a look beyond the Endangered Species Act and suggests additional means of biological conservation and ways to reduce conflicts. It will be useful to policymakers, regulators, scientists, natural-resource managers, industry and environmental organizations, and those interested in biological conservation.
ONE OF THE NEW YORK TIMES BOOK REVIEW'S 10 BEST BOOKS OF THE YEAR A major book about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes Over the last half a billion years, there have been five mass extinctions, when the diversity of life on earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In The Sixth Extinction, two-time winner of the National Magazine Award and New Yorker writer Elizabeth Kolbert draws on the work of scores of researchers in half a dozen disciplines, accompanying many of them into the field: geologists who study deep ocean cores, botanists who follow the tree line as it climbs up the Andes, marine biologists who dive off the Great Barrier Reef. She introduces us to a dozen species, some already gone, others facing extinction, including the Panamian golden frog, staghorn coral, the great auk, and the Sumatran rhino. Through these stories, Kolbert provides a moving account of the disappearances occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up through the present day. The sixth extinction is likely to be mankind's most lasting legacy; as Kolbert observes, it compels us to rethink the fundamental question of what it means to be human.
Everyone is familiar with the dodo and the wooly mammoth, but how many people have heard of the scimitar cat and the Falkland Island fox? Extinct Animals portrays over 60 remarkable animals that have been lost forever during the relatively recent geological past. Each entry provides a concise discussion of the history of the animal—how and where it lived, and how it became extinct—as well as the scientific discovery and analysis of the creature. In addition, this work examines what led to extinction—from the role of cyclical swings in the Earth's climate to the spread of humans and their activities. Many scientists believe that we are in the middle of a mass extinction right now, caused by the human undermining of the earth's complex systems that support life. Understanding what caused the extinction of animals in the past may help us understand and prevent the extinction of species in the future. Extinct Animals examines the biology and history of some of the most interesting creatures that have ever lived, including: The American Terror Bird, which probably became extinct over 1 million years ago, who were massive predators, some of which were almost 10 feet tall; the Rocky Mountain Locust, last seen in 1902, formed the most immense animal aggregations ever known, with swarms estimated to include over 10 trillion insects; the Giant Ground Sloth, which was as large as an elephant; and the Neandertals, the first Europeans, which co-existed with prehistoric Homo sapiens. Extinct Animals includes illustrations—many created for the work—that help the reader visualize the extinct creature, and each entry concludes with a list of resources for those who wish to do further research.

In the twenty-first century, because of climate change and other human activities, many animal species have become extinct, and many others are at risk of extinction. Once they are gone, we cannot bring them back—or can we? With techniques such as cloning, scientists want to reverse extinction and return lost species to the wild. Some scientists want to create clones of recently extinct animals, while others want to make new hybrid animals. Many people are opposed to de-extinction. Some critics say that the work diverts attention from efforts to save species that are endangered. Others say that de-extinction amounts to scientists "playing God." Explore the pros and cons of de-extinction and the cutting-edge science that makes it possible.
Jurassic Park meets The Sixth Extinction in Rise of the Necrofauna, a provocative look at de-extinction from acclaimed documentarist and science writer Britt Wray. A New Yorker “The Books We Loved in 2017” Selection A Science News Favorite Book of 2017 A Sunday Times "Must Read" What happens when you try to recreate a woolly mammoth—fascinating science, or conservation catastrophe? In Rise of the Necrofauna, Wray takes us deep into the minds and labs of some of the world's most progressive thinkers to find out. She introduces us to renowned futurists like Stewart Brand and scientists like George Church, who are harnessing the powers of CRISPR gene editing in the hopes of "reviving" extinct passenger pigeons, woolly mammoths, and heath hens. She speaks with Nikita Zimov, who together with his eclectic father Sergey, is creating Siberia's Pleistocene Park—a daring attempt to rebuild the mammoth's ancient ecosystem in order to save earth from climate disaster. Through interviews with these and other thought leaders, Wray reveals the many incredible opportunities for research and conservation made possible by this emerging new field. But we also hear from more cautionary voices, like those of researcher and award-winning author Beth Shapiro (How to Clone a Woolly Mammoth) and environmental philosopher Thomas van Dooren. Writing with passion and perspective, Wray delves into the larger questions that come with this incredible new science, reminding us that de-extinction could bring just as many dangers as it does possibilities. What happens, for example, when we bring an "unextinct" creature back into the wild? How can we care for these strange animals and ensure their comfort and safety—not to mention our own? And what does de-extinction mean for those species that are currently endangered? Is it really ethical to bring back an extinct passenger pigeon, for example, when countless other birds today will face the same fate? By unpacking the many biological, technological, ethical, environmental, and legal questions raised by this fascinating new field, Wray offers a captivating look at the best and worst of resurrection science. A captivating whirlwind tour through the birth and early life of the scientific idea known as “de-extinction.”—Beth Shapiro, author of How to Clone a Mammoth: The Science of De-Extinction Published in Partnership with the David Suzuki Institute.
This book of photography represents National Geographic's Photo Ark, a major cross-platform initiative and lifelong project by photographer Joel Sartore to make portraits of the world's animals -- especially those that are endangered. His message: to know these animals is to save them. Sartore intends to photograph every animal in captivity in the world. He is circling the globe, visiting zoos and wildlife rescue centers to create studio portraits of 12,000 species, with an emphasis on those facing extinction. He has photographed more than 6,000 already and now, thanks to a multi-year partnership with National Geographic, he may reach his goal. This book showcases his animal portraits: from tiny to mammoth, from the Florida grasshopper sparrow to the greater one-horned rhinoceros. Paired with the prose of veteran wildlife writer Douglas Chadwick, this book presents an argument for saving all the species of our planet.
A Gap in Nature by Tim Fridtjof Flannery,Peter Schouten Pdf
We live in an age of extinction. A Gap in Nature, written by Tim Flannery and breathtakingly illustrated by Peter Schouten, tells the magic story of how, after Columbus' bold discovery of the Americas in 1492, the impact of European exploration and settlement was to prove fatal for many of the planet's most bizarre and extraordinary creatures. Some species disappeared before they could be properly documented, and others became extinct when overzealous collectors shot their last members. Every part of the planet was affected, from the Caribbean to the Arctic North, from the tiniest Pacific island to Eurasia, the great landmass of them all.
Tipping Point for Planet Earth by Anthony D. Barnosky,Elizabeth A. Hadly Pdf
Four people are born every second of every day. Conservative estimates suggest that there will be 10 billion people on Earth by 2050. That is billions more than the natural resources of our planet can sustain without big changes in how we use and manage them. So what happens when vast population growth endangers the world’s food supplies? Or our water? Our energy needs, climate, or environment? Or the planet’s biodiversity? What happens if some or all of these become critical at once? Just what is our future? In Tipping Point for Planet Earth, world-renowned scientists Anthony Barnosky and Elizabeth Hadly explain the growing threats to humanity as the planet edges toward resource wars for remaining space, food, oil, and water. And as they show, these wars are not the nightmares of a dystopian future, but are already happening today. Finally, they ask: at what point will inaction lead to the break-up of the intricate workings of the global society? The planet is in danger now, but the solutions, as Barnosky and Hadly show, are still available. We still have the chance to avoid the tipping point and to make the future better. But this window of opportunity will shut within ten to twenty years. Tipping Point for Planet Earth is the wake-up call we need.

A New York Times Book Review Editors' Choice What Saladino finds in his adventures are people with soul-deep relationships to their food. This is not the decadence or the preciousness we might associate with a word like “foodie,” but a form of reverence . . . Enchanting." —Molly Young, The New York Times Dan Saladino's Eating to Extinction is the prominent broadcaster’s pathbreaking tour of the world’s vanishing foods and his argument for why they matter now more than ever Over the past several decades, globalization has homogenized what we eat, and done so ruthlessly. The numbers are stark: Of the roughly six thousand different plants once consumed by human beings, only nine remain major staples today. Just three of these—rice, wheat, and corn—now provide fifty percent of all our calories. Dig deeper and the trends are more worrisome still: The source of much of the world’s food—seeds—is mostly in the control of just four corporations. Ninety-five percent of milk consumed in the United States comes from a single breed of cow. Half of all the world’s cheese is made with bacteria or enzymes made by one company. And one in four beers drunk around the world is the product of one brewer. If it strikes you that everything is starting to taste the same wherever you are in the world, you’re by no means alone. This matters: when we lose diversity and foods become endangered, we not only risk the loss of traditional foodways, but also of flavors, smells, and textures that may never be experienced again. And the consolidation of our food has other steep costs, including a lack of resilience in the face of climate change, pests, and parasites. Our food monoculture is a threat to our health—and to the planet. In Eating to Extinction, the distinguished BBC food journalist Dan Saladino travels the world to experience and document our most at-risk foods before it’s too late. He tells the fascinating stories of the people who continue to cultivate, forage, hunt, cook, and consume what the rest of us have forgotten or didn’t even know existed. Take honey—not the familiar product sold in plastic bottles, but the wild honey gathered by the Hadza people of East Africa, whose diet consists of eight hundred different plants and animals and who communicate with birds in order to locate bees’ nests. Or consider murnong—once the staple food of Aboriginal Australians, this small root vegetable with the sweet taste of coconut is undergoing a revival after nearly being driven to extinction. And in Sierra Leone, there are just a few surviving stenophylla trees, a plant species now considered crucial to the future of coffee. From an Indigenous American chef refining precolonial recipes to farmers tending Geechee red peas on the Sea Islands of Georgia, the individuals profiled in Eating to Extinction are essential guides to treasured foods that have endured in the face of rampant sameness and standardization. They also provide a roadmap to a food system that is healthier, more robust, and, above all, richer in flavor and meaning.
Extinct Animals of the British Isles by Gerlach Justin Pdf
136 animal species have become extinct in the British Isles over the past thousand years. This book describes many of these extinctions, from familiar species such as the wolf and the iconic extinction of the great auk, to the numerous insects that have vanished from the islands.
The passenger pigeon, the great auk, the Tasmanian tiger—the memory of these vanished species haunts the fight against extinction. Seeking to save other creatures from their fate in an age of accelerating biodiversity loss, wildlife advocates have become captivated by a narrative of heroic conservation efforts. A range of technological and policy strategies, from the traditional, such as regulations and refuges, to the novel—the scientific wizardry of genetic engineering and synthetic biology—seemingly promise solutions to the extinction crisis. In The Fall of the Wild, Ben A. Minteer calls for reflection on the ethical dilemmas of species loss and recovery in an increasingly human-driven world. He asks an unsettling but necessary question: Might our well-meaning efforts to save and restore wildlife pose a threat to the ideal of preserving a world that isn’t completely under the human thumb? Minteer probes the tension between our impulse to do whatever it takes and the risk of pursuing strategies that undermine our broader commitment to the preservation of wildness. From collecting wildlife specimens for museums and the wilderness aspirations of zoos to visions of “assisted colonization” of new habitats and high-tech attempts to revive long-extinct species, he explores the scientific and ethical concerns vexing conservation today. The Fall of the Wild is a nuanced treatment of the deeper moral issues underpinning the quest to save species on the brink of extinction and an accessible intervention in debates over the principles and practice of nature conservation.
